Comparison of Three Different Suture Materials for Toggle Pin (TP) Technique in Induced Hip luxation in Dogs

Abstract

This research was performed at Veterinary Surgery clinic, Faculty of Veterinary Medicine, Zagazig University, Egypt to compare between three different suture materials for toggle pin technique in induced hip luxation in dogs. This comparison includes complications during surgery and post-operative clinical evaluation of each case. The study was conducted on12 apparently healthy mongrel dogs (dewormed and quarantined for 2 weeks). These animals were preoperatively evaluated for normal hip joint by X-ray, and then were subjected to induced hip luxation. The twelve dogs were divided into 3 groups based on the type of suture materials. The first group was toggle pin (TP) using monofilament polypropylene suture material2USP. The second group was TP using multifilament polyester suture material 5USP. The third group was TP using stainless steel wire size 0.5mm. Evaluation of these animals post-operative was conducted based on visual pain assessment, lameness scoring, and luxation recurrence radiographically. The monofilament polypropylene suture material 2USP used for the 1st group (4dogs) was found excellent in manipulation and not easily cut post-operative with minimal complications. The multifilament polyester suture material 5USP used for the 2nd group (6 dogs) was not tolerant where it cut during surgery in 4 cases and 1 week post-operative in 2 cases. The stainless steel wire used for the 3rd group (2 dogs) was difficult to be manipulated during surgery, then femoral head was re-luxated and the wire cut 1 week and 3 weeks post-operative, respectively. The findings of this study proved that monofilament Polypropylene suture material 2 USP was the best material for suturing in TP technique followed by multifilament polyester 5 USP, and finally with stainless steel wire size 0.5mm.
